I've been away from the board lately.

I opened the the above .bin in my EFI Live software. I see you are using OS 12225074.

I noticed you are using a 24x CKP sensor. So am I correct you are using a per-coil ignition system?

I have a similar project, 406 SBC 4x CKP with a Vortec distributor. I'm using OS 12212156 from a 2002 Express Van.

I have the ability to Flash an '0411 PCM with EFI Live .ctz files and then read back the Flashed .ctz file as a .bin file.

Maybe you could post a modified EFI Live .ctz file you have setup for the 406 SBC, then I can post a .bin file you can flash?

I am unable to help you with TunerPro OBD II tuning.
